Thank you! [1/1] arm64: dts: ti: k3-am64: Add ESM0 to device memory map commit: 2aeb0696b8e801c20c2176d9dbe512b6a5aa2f79 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent up the chain during the next merge window (or sooner if it is a relevant bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. [1] git://git.kernel.org/pub/scm/linux/kernel/git/ti/linux.git

AM64x SoCs have two ESM modules, with one in MAIN voltage domain and the other in MCU voltage domain. The error output from Main ESM module can be routed to the MCU ESM module. The error output of MCU ESM can be configured to reset the device. The MCU ESM configuration address space is already opened and this patch opens the MAIN ESM configuration address space. For ESM details please refer technical reference manual at https://www.ti.com/lit/pdf/spruim2 Signed-off-by: Hari Nagalla <hnagalla@ti.com> --- arch/arm64/boot/dts/ti/k3-am64.dtsi | 1 + 1 file changed, 1 insertion(+)
